Matthew 5:32

But now I’m telling you this, husbands and wives have to stay married to each other. Only if a man’s wife sleeps with another man, as if he is her husband, only then can her proper husband divorce her. But if a wife never does that, her husband can’t divorce her. If he divorces her, he is forcing her to go and sleep with another man, and that is wrong. And if another man marries her, he is doing wrong too.”⋮
